Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

What are best practices for day/night lightmaps?

so I was thinking, if I have a day and night cycle does it still make sense to adopt lightmaps ? I mean from what I know there can be just one lightmap per asset and wouldn't it look wrong to have day baked lightmaps at night or night baked lightmaps during the day ?

is there any workaround/best practices you guys know that I don't ? any help would be very appreciated :)

This would depend on what you're goal is for your style of game. If you're using a day/night cycle with a movable light it may not be the best solution though. You can still have lights that bake lightmaps for certain areas though. For instance, if you have an interior area that will never be affected by the directional light then it may be in your best interest there to use baked lightmaps. If it's in the environment it may only work to have certain objects cast a static lightmap shadow. The best solution would be to do a simple test with assets once you get your day/night cycle working right.

If you have any specific instances or questions feel free to ask! :)
